TOP ROLLER FOR DRAWENG-FRAMES, 631,0.

SECEFEGATION forming part of Letters Patent No. 319,187, dated June 2,1885.

Application (lied June 2, 1884.

To @ZZ whom it may concern:

Be it known that I, JOHN BarnnLnY, of East Hamptoinin the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvemnts in Top Rollers for Drawing and other Frames for lVorking Cotton, of which the following is a full, clear, and exact description.

This invention has for its object the providing, with positively-driven top rollers, different frames or machines used incotton-mills-such as drawing-frames, slubbers, speeders, spinning frames and mules-in which the sliver, roving, or yarn is passed between bottom and top rollers. Ordinarily said frames, which Y are some thirty i'eet (more or less) in length,

have the top rollers, that are faced with leather and are driven by frictionfrom the iluted oriongitudinally-grooved lower rollers, arranged, unlike the continuous or connected lower rollers, separate or in pairs throughout the whole length or series of them, partitions, known as cap-bars, being made in the frame between each double roller.

The invention consists of the combination, with two or more series of bottom rollers, of two or more series of clothed top rollers coupled together in each series at their ends,and geared with the bottom rollers, over which they are arranged to operate in unison therewith, and whereby the coupled top rollers are positively driven by the bottom rollers.

It consists, further, of series of coupled top rollers combined with continuous bottom rollers and gears, substantially as hereinafter more fully set forth and claimed.

By thus using positively-driven top rollers the same are not liable to slip, as they are under the old construction,hereinbefore referred to; but they will or must or' necessity make the same number of revolutions in a given time as the lower rollers. rlhis will produce more perfect worlninasmuch as when atop roller of a speeder-frame slips it fails to give the proper length of sliver or roving to the iiicr and bobbin of the machine, said ilier and bobbin being driven by gears and regulated to take on exactly the same length of sliver or roving as should be delivered by the rollers, so that if the top roller slips the proper length of sliver or roving is not delivered, and the bobbin stretches the length of Vfiberbetween it (No model.)

and the rollers, thus making uneven places in the sliver on a drawing-frame in the roving Of'speeders and in the yarn of spinning frames and mules. All this is avoided by using positively-driven top rollers. Lighter weights, too, may be used on the levers ordinarily employed in such machines or frames to hold or bear down the top rollers, and this may be done without injury to the worl,and such will greatly reduce the power necessary to drive all the rollers. Neither will there be any sliding or slipping friction on the leather clothings oi' the top rollers, and less weight being thrown on said rollers their leather coverings will be much more durable.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l represents a broken top view of a Speeder-frame in part-,having three sets of upper rollers and a corresponding number of lower rollers, arranged for passage of the roving in between them, the front and intermediate series of top rollers being positively'- driven ones, in accordance with myinvention, but the back set or series being shown disconnected, or of the ordinary construction, although they, too, may or should be positivelydriven ones. Fig. 2 is an end view; Fig. 3,a vertical transverse section on the line x c in Fig. l, and Fig. 4 a similar sectional view on the line y y in Fig. l.

A A are the ends of the frame, and B B B three parallel sets or series of bottom rollers, each series being made up oi a succession of iluted or ribbed connected rollers or rollersurfaces between the two ends A A of the frame, as usual.

C Gand Gindicate three corresponding series of upper rollers faced o r clothed with leather, and between which and the lower rollers the rovingD is passed. The front and middle series, C C, of these upper rollers, as well as the back series, C', are made up,as usual,of a succession of double rollers-that is, two rollersin the same line with a reduced portion or bearing in be tween them-but as here shown for the two series C C only, though intended to be applied to the remaining series C as well. lnstead of separating each succeeding pair of double rollers by cap-bars in the frame, and

IOD

driving them by friction from the bottom rollers, the ends b b of each upper roller or double roller C C are extended through the spaces usually occupied by the cap-bars or partitions, and are divided or cut away longitudinally for a portion of their length, so as to forni a lap-joint, c, the one roller with the other, whereby, although separate and so that the several double rollersin the same line may be separately removed and replaced when required, each double roller Gis made the driver of the next double roller in the same row, and and by gearing such coupled double upper rollers in each row at the one end thereof by gears d @with the bottom roller, B,of continuous or permanently-connected rollers, over and with which they are designed to work,the upper rollers, C C, become positive or positively-driven ones, as and for the purposes hereinbefore set forth.

E E are the usual weighted levers, provided with suitable connections for holding down the top rollers to their work.

Having thus described my invention,l claim as new and desire to secure by Letters Patent- 1. The combination, with two or more series of. bottom rollers, B B, of two or, more series of clothed top rollers, C C, coupled together in each series by lap-joints c cat their ends, and gears d e, said top rollers, being geared with the bottom rollers, over which they are arranged to operate in unison therewith, and whereby the coupled top rollers are positively driven by the bottom rollers, essentially as described.

2. The series of coupled top rollers, C C, in combination with the continuous bottom rollers, B B, and the gearsde, the upper and lower coincident or opposite rollers thereof being geared together, substantially as specified.
